First Claim
1. A metallic golf club head having a hollow interior, comprisinga) a ball-striking front wall, and the head having walls at the top, bottom, rear, heel, and toe of the head,b) said front wall having variable thickness between the heel and toe to transmit golf striking impact forces from the head front wall to said top wall without cracking or buckling of said front wall or top wall,c) said front wall also having an additional locally rearwardly thickened and bulging portion which extends in a direction toward the heel from a mid-region of the front wall toward and proximate to a peripheral region of the front wall,d) the locally rearwardly thickened and bulging portion also being metallically integral with said front face directly forwardly of said bulging portion,e) said head having a shaft receiving tube interiorly of the head and proximate said heel, and located proximate said locally rearwardly thickened and bulging portion.

2. A metallic golf club head having a hollow interior, comprising
a) a ball-striking front wall, and the head having walls at the top, bottom, rear, heel, and toe of the head, said head having a shaft receiving tube interiorly of the head and proximate the heel, b) said front wall having variable thickness between the heel and toe to transmit golf striking impact forces from the head front wall to said top wall without cracking or buckling of said front wall or top wall, c) said variable thickness in upper regions of said front wall decreasing from an upper mid-region in a direction toward said toe and from said upper mid-region in a direction toward said heel and directly forwardly of said tube, said upper mid-region being defined by an upper region of said front wall about mid-way between the toe and heel, d) said front wall also having an additional locally rearwardly thickened and bulging portion which extends in a direction toward the heel from a mid-region of the front wall toward and proximate to a peripheral region of the front wall.

20. A metallic golf club head having a hollow interior, comprising
a) a ball-striking front wall, and the head having walls at the top, bottom, rear, heel, and toe of the head, said head having a shaft receiving tube interiorly of the head and proximate the heel, b) said front wall having variable thickness between the heel and toe to transmit golf striking impact forces from the head front wall to said top wall without cracking or bulking of said front wall or top wall, c) said variable thickness in upper regions of said front wall decreasing from an upper mid-region in a direction toward said toe and from said upper mid-region in a direction toward said heel and directly forwardly of said tube, said upper mid-region being defined by an upper region of said front wall about mid-way between the toe and heel, d) a metallic hosel integral with the head and located within the interior thereof and proximate said variable thickness front wall and said variable thickness existing at locations proximate a merging connection of said front wall and said top wall, e) a first group of narrow, metallic, shock wave distributing dendrites extending from said variable thickness front wall generally rearwardly adjacent the underside of the top wall and integral therewith, f) the endrites spaced apart by amounts greater than their widths, the maximum height dimensions of the dendrites below the underside of the top wall being between 0.050 inches and 0.100 inches and the dendrites being generally downwardly convex in cross-section g) and a second group of narrow metallic dendrites which are integral with said rear wall and extend downwardly at the inner side of said rear wall, said dendrites of the second group being located further from the front wall than the dendrites of the first group, h) and wherein the dendrites of the second group also extend beneath said top wall and are spaced apart in a transverse direction, the maximum height dimensions of the second group dendrites being between 0.050 and 0.100 inches.

21. A metallic golf club head having a hollow interior and comprising
a) a ball-striking, upright front wall, and the head having walls at the top, bottom, rear, heel, and toe of the head, b) said front wall having a locally rearwardly thickened portion which extends in a direction from a mid-region of the front wall toward a peripheral region of the front wall, c) there being a hosel tube which is within the head and proximate the heel and toward which said locally rearwardly thickened portion closely extends, d) said front wall also having an additional locally rearwardly thickened and bulging portion which extends in a direction toward the heel from a mid-region of the front wall toward and proximate to a peripheral region of the front wall.

32. In a golf club, of the type including a head and a shaft with a first end, a portion of the shaft proximate said first end being attached to a head, the head comprising a hollow metal shell having a ball striking front wall having a striking surface, a top wall portion, a bottom portion, a toe portion, and a heel wall furthest from said toe portion, said top wall portion being substantially continuous from said toe portion to said heel portion, the improvement comprising:
-
a) a substantially continuous hollow, metallic tube extending lengthwise along a shell wall from the shell top portion to the shell bottom portion, said tube being integral with and terminating proximate said metal shell top portion and having a bore, b) the tube bore receiving the shaft, c) the shaft periphery, connected to the tube bore, and the tube bore having an upper end terminating proximate said shell top portion, d) the tube integrated with said shell wall so that the shell supports the tube along its length, and whereby metal otherwise required for the tube is used in the shell at locations between the tube and said toe portion, e) said front wall having variable thickness between the heel portion and the toe portion, and extending directly forwardly of said tube. - View Dependent Claims (33, 34, 35, 36, 37, 38, 39)

40. In a golf club, of the type including a head and a shaft with a first end, a portion of the shaft proximate said first end being attached to a head, the head comprising a hollow metal shell having a ball striking front wall having a striking surface, a top wall, a bottom wall, a toe portion, and a heel portion furthest from said toe portion, the improvement comprising:
-
a) a substantially continuous hollow, metallic, hosel tube extending within said metal shell at the heel portion from the shell top wall to the shell bottom wall, said tube being integral with and terminating proximate said metal shell top wall, and having a bore, said heel portion including a heel wall merged with a rearwardmost extent of said tube, b) the tube bore receiving a portion of the first end of the shaft, and there being means connecting the shaft periphery to the tube bore, c) said front wall having variable thickness between said toe portion and said heel portion, said variable thickness decreasing in a direction toward the toe, and in a direction toward the heel to extend directly forwardly of said tube.

41. A method of attaching a metal golf club head to a shaft, comprising the steps of:
-
a) providing metal golf club head with a top surface, a bottom surface, a front wall having a ball-striking surface with an uppermost extent, a rear surface, a heel portion, a toe portion, and a substantially continuous hollow tube extending between thee top surface, and the bottom surface near the heel portion, said tube being formed to have an upper end terminating proximate the level of said uppermost extent of said striking surface, and proximate an upper most extent of said heel end, b) forming said front wall to have variable thickness between said toe portion and said heel portion proximate said tube, c) and inserting the lower end of the shaft into the tube with an adhesive material applied between the exterior surface of the shaft and the interior wall of the tube, the shaft being inserted so that the lower end of the shaft extends proximate said bottom surface, d) said front wall variable thickness also provided to decrease in a direction toward and into proximity to said tube. - View Dependent Claims (42, 43, 44)
